This foundation layout drawing for a 17.6 MVA Inverter Control Room (ICR) shows isolated reinforced concrete footings at a depth of -1.5m from natural ground level. This drawing details three types of footings (F1, F2, F3) with their respective dimensions and reinforcement schedules. F1 footings measure 4000×2700×350mm with Y12@100mm c/c bottom reinforcement. F2 footings are 5000×2600×350mm, while F3 footings are 3000×3000×300mm. The drawing includes typical sections showing pedestal details (P1 size 450×450mm) with 4-Y20 main reinforcement and Y8@100mm c/c stirrups. Ground improvement specifications require 800-1200mm soil replacement with granular fill compacted to 95% MDD. All concrete is specified as M30 grade with CRS/FBEC rebar (Fe500 grade). The foundation supports multiple equipment pieces including 4.4MW inverters, transformers, auxiliary panels, and NIFPS systems for a 300 MWac solar ground-mounted project in Khavda, Gujarat.
